Title: Polyvinyl oleate as a fat replacement
Inventor: D AMELIA RONALD P
IPC: A23L33/20
Filed: 1989-12-18
Abstract: POLYVINYL OLEATE AS A FAT REPLACEMENT                 ABSTRACT OF THE DISCLOSURE        Polyvinyl alcohol fatty acid esters, notably unsaturated acid esters, comprise a new class of edible fat replacements.  Polyvinyl oleate, prepared either by direct esterification of low molecular weight polyvinyl alcohol with oleic acid, oleic anhydride or oleyl chloride, by the transesterification between low molecular weight polyvinyl alcohol and methyl oleate, or by the interesterification between low molecular weight polyvinyl acetate and methyl oleate, is a preferred edible fat replacement.

Title: Process and apparatus for controlling distribution of thread on a package in a collection unit for synthetic threads
Inventor: PRODI PAOLO
IPC: B65H54/38
Filed: 1989-12-22
Abstract: 1.     "PROCESS  AND APPARATUS FOR CONTROLLING    DISTRIBUTION  OF THREAD ON A PACKAGE IN A COLLECTION UNIT FOR SYNTHETIC THREADS"                       Abstract The  present  invention  relates to a  process  for piloting  the  distribution of the thread on  the package under  formation,  in  a collection unit  for  collecting synthetic  threads,  so  as  to  prevent  ribbness    from forming during    the continuous overlapping of different winding  layers,  so  as  to render easy and  simple  the subsequent technologic operations which the thread of the package has to be submitted to.    The  present  invention furthermore  relates  to  an apparatus   for  the  practioal  implementation  of   the process,  which  substiantially consists in setting, instant  by  instant,   the  values  of  the  operational parameters  during the thread winding in such a way  that the collection unit operates along descending portions of lines,  with  each being defined by a    constant  and  non-integer "winding ratio" "K",  and in containing said line portions  inside  a range bounded by a maximum  threshold value and a minimum threshold value of the winding angle, with  said  maximum and minimum  threshold  values  being symmetrical  relatively  to  the value  regarded  as  the 2. optimum  one,  for the package under  formation,  and  in furthermore  piloting the traverse      cam in  order to  fix the dislocation of said descending line  portions at  a  distance higher than,  or   at least equal  to,  a prefixed reference value,  from a whatever line belonging to  the group of "integer-K-value" lines,  or of  "exact-fraction-K-value" lines, which represent, as a whole, the orders  of ribbness caused by  the  "mirror  effects", regarded  as detrimental to the winding which  is  taking place.

Abstract: Abstract of the Disclosure A controller for an injection molding machine controls the injection ram by means of profiles having segments with programmable setpoints.  The injection molding machine is initially controlled during each segment in an open-loop manner.  Closed-loop control is then adopted.  The difference between the process signal, e.g. ram velocity, and the setpoint at the end of each segment is used to change the current setpoint to improve the open-loop accuracy over time.  The learning rate of change of the open-loop setpoints decreases after the initial correction.

The engine speed sensor shuts down the system if the engine is not running and functions by sensing the AC signal component that is superimposed on the vehicle DC power supply when the engine is running.   In an alternative embodiment, the U-shaped heating tube is replaced by a hollow aluminum vessel having an internal fluid chamber. Cleaning fluid is held in the fluid chamber and heated by a plurality of metal heating fins or pins that extend into the fluid chamber.  The heating fins or pins are heated by a plurality of PTC thermistors positioned on the outside of the aluminum vessel. The heating process is controlled by a control circuit connected to the plurality of thermistors.
